Resolved: Thanks for the help, everyone! The script by Sergey Kritskiy works to export storyboards with sequential file-name.
I just found a script by TunaMaxx the other day and thought it was super helpful to export my storyboards.
Right now it exports the entire first column, then 2nd column then 3rd and 4th column. I end up with my boards labeled in the wrong order of "1, 5, 9, 13" then "2, 6, 10, 14" and so on. (images below)
I was wondering if it's possible to somehow have it export it by rows, so my boards are saved/titled as "1, 2, 3 ,4..,etc?" It seems like not a big deal, but when I'm exporting 200+ boards, it's a hassle to go back and re-organize all of this. (Without the script, I resort to creating guide lines and using slice tool.)
I included screenshots below of what I'm looking for in photoshop and what it looks like after the export.
